12. A bus on a regular schedule takes 3 14 hour
express?
O A. 34 hours
O B. 1 14 hours
O C. 2 hours
O D. 534 hour
Answer:
3 1/4 hours = 3 + 1/4 = 3 + 0.25 = 3.25. 2 1/2 hours = 2 + 1/2 = 2.5. To find out how much travel time can be saved by taking the express, simply subtract its travel time (which is shorter) from the regular's one. So 3.25 - 2.5 = 0.75 or 3/4.

The table shows pricing information for two pizzas. How many toppings would
number 13 only
The number of toppings where the cost of each pizza would be equal is 5.
How many toppings would make the pizza equal?The first step is to formulate an equation that represents the cost of each type of pizza.
Total cost = price of cheese pizza + (price per topping x number of toppings)
Cost of pizza A = $10 + $1.50t
Cost of pizza B = $12.50 + t
When the cost of both pizzas are equal, the above equations would be equal to each other.
$10 + $1.50t = $12.50 + t
To determine the value of t, take the following steps:
Combine similar terms: 1.50t - t = $12.50 - $10
Add similar terms = 0.50t = 2,50
Divide both sides by 0.50 = t = 2.50 / 0.50
t = 5

What is x - intercept and y - intercepts?
The x-intercept is the location where a line's graph crosses the x-axis.
The y-intercept is the location where a line's graph crosses the y-axis.
The shapes of these points are (x,0) and (0,y), respectively.
Utilize the fact that all x-intercepts have a y-value of zero and all y-intercepts have an x-value of zero to get the x- and y-intercepts algebraically.

Step-by-step explanation:
so, first $300 must be paid without any ifs and whens.
for the rest of the amount the insurance will cover 70%.
the bills total to
700 + 930 = $1630
he must pay $300 of that directly.
that leaves 1630 - 300 = $1330 for the 70/30 split between insurance and patient.
the patient must pay 30% of these $1330.
100% = 1330
1% = 100%/100 = 1330/100 = $13.30
30% = 1% × 30 = 13.30 × 30 = $399
so, the patient pays
300 + 399 = $699
of the $1630 bill.

if the hypotenus of a right triangle is 6 m and one side is 4 m, what's the length of the other side
Answer:
[tex]\sqrt{20} \text{ or } 2\sqrt{5}[/tex]
Step-by-step explanation:
So in this question we want to use the Pythagorean Theorem which essentially gives us a relationship between the sides of a triangle and is as follows: [tex]a^2+b^2=c^2[/tex]
In this formula the "a" and "b" represent the base and the height and "c" represents the hypotenuse of the triangle
The order in which you assign "a" and "b" do not matter, so let's just say that: [tex]a=4\ \text{and}\ c=6[/tex]
Although it is important that you assign the hypotenuse to "c".
So plugging in known values we have the equation:
[tex]4^2 +b^2=6^2[/tex]
Square the values
[tex]16+b^2=36[/tex]
Subtract1 16 from both sides
[tex]b^2=20[/tex]
take the square root of both sides
[tex]b=\sqrt{20}[/tex]
This "b" represents our other side, which we did not initially know, so this is our answer :)
You can simplify this further by separating the radical into: [tex]\sqrt{20} = \sqrt{4} * \sqrt{5} = 2\sqrt{5}[/tex]

how do I write in slope-intercept form the points (-3, 0); slope=2/3
The equation of line can be written as, y = 2/3x + 2
Given,
The points, (x, y) = (-3, 0)
Slope = 2/3
Equation of a line, y = mx + c
Where, m is the slope and c is the y-intercept.
Here, m is 2/3.
The point at the x-intercept has co-ordinates : (-3, 0)
Where, x is -3 and y is 0.
So, substitute the values in equation:
y = mx + c
0 = 2/3 × (-3) + c
0 = -2 + c
c = 2

Bill Murray has 16 3/4 days of vacation per year. To date, he has taken 1 3/4 days in January, 4 2/3 days in February, and 2 1/6 days in March. How much more vacation time is Bill entitled to?
Step-by-step explanation:
16 3/4 days in total.
that are (16×4 + 3)/4 = 67/4 days.
he has taken
1 3/4 = (1×4 + 3)/4 = 7/4 days
4 2/3 = (4×3 + 2)/3 = 14/3 days
2 1/6 = (2×6 + 1) = 13/6 days
to be able to add abd subtract them directly, we need to bring all fractions to the same denominator.
we have 3, 4, 6 : the smallest common multiple is 12 (can be divided without remainder by 3, 4 and 6).
we need to multiply each fraction by a fitting n/n factor to bring the denominators to 12 and keep the overall value of the fraction unchanged.
67/4 = 67/4 × 3/3 = 201/12
7/4 = 7/4 × 3/3 = 21/12
14/3 = 14/3 × 4/4 = 56/12
13/6 = 13/6 × 2/2 = 26/12
the remaining vacation time is
201/12 - 21/12 - 56/12 - 26/12 = 98/12 = 49/6
49/6 = 8 and remainder 1 = (8×6 + 1)/6 = 8 1/6 days

Find the formula for p(x)
P(x)=
the formula for the polynomial is:
p(x) = (-3/10)*(x - 2)^2*(x + 5)
How to find the formula for p(x)?Here we have a polynomial with the following roots:
x = 2, with a multiplicity of 2.x = -5 with a multiplicity of 1.So, if we define A as the leading coefficient, we can write the polynomial as:
p(x) = A*(x - 2)^2*(x + 5)
We know that the y-intercept is -6, so evaluating in x = 0 we should get:
p(0) = -6 = A*(0 - 2)^2*(0 + 5) = A*4*5 = A*20
-6/20 = A = -3/10
Then the formula for the polynomial is:

If the parent function f(x) = |x| is transformed to g(x) = |x + 5|, what transformation occurs from f(x) to g(x)?
The transformation that occurs from f(x) to g(x) is the graph of f(x) is shifted to the left to create g(x).
What transformation occurs from f(x) to g(x)?The equations of the functions are given as
f(x) = |x|
g(x) = |x + 3|
The above implies that
g(x) = f(x + 3)
When a function is shifted to the left by h units, it is represented as
g(x) = f(x + h)
This means that
h = 3
So, the transformation that occurs from f(x) to g(x) is the graph of f(x) is shifted to the left to create g(x).
Hence, the required transformation that occurs from f(x) to g(x) is the graph of f(x) is shifted to the left to create g(x).
